To ensure separability of rows, codewords of consecutive rows belong to different subsets of all possible codewords. This routine scans the symbols in the barcode. When it finds a number of consecutive rows which are the same, it assumes that this is a row of codewords and processes them into a codeword array.

2012-\/09-\/12 H\+FN\+: Because now, at an earlier stage, the Detector has counted the rows, now it is no more necessary to check the equality of consecutive rows. We now have to check every row.

\begin{DoxyReturn}{Returns}
an array of codewords. 
\end{DoxyReturn}

\begin{DoxyExceptions}{Exceptions}
{\em \mbox{\hyperlink{classzxing_1_1_format_exception}{Format\+Exception}}} & for example if number of rows is too big or something with row processing is bad \\
